resedimentation

resedimentation

[rē‚sed·ə·mən′tā·shən]
(geology)
Sedimentation of material derived from a preexisting sedimentary rock, that is, redeposition of sedimentary material.
Mechanical deposition of material in cavities of postdepositional age, such as the deposition of carbonate muds and silts by internal mechanical erosion or solution of a limestone.
The general process of subaqueous, downslope movement of sediment under the influence of gravity, such as the formation of a turbidity-current deposit.

Thin-shelled bivalves such as Pectinidae from fine quartz sands are generally represented by small fragments, this means resedimentation process in situ or an incipient reworking.
But after Vietnam's communist government opened the economy in 1986 and encouraged rice exports, villagers used their growing wealth to drill private wells, which strained groundwater resources and disrupted a centuries-old system that favored resedimentation. More than a million wells have since been drilled into the Mekong Delta, and subsidence has been accelerating ever since.
Resedimentation of the late Holocene White River tephra, Yukon Territory and Alaska.
Deposits formed by supraglacial processes are better known, but more complex, because sedimentation occurs on an unstable substrate (ice) and superglacial deposits commonly undergo several episodes of reworking or resedimentation prior to final deposition.
Tectonics is an additional factor to the eustatic and climate influences that increase the likelihood of resedimentation. The Cutri Formation was deposited during a rifting stage.
